Davis, OK Tap Water Quality

Tap water in Davis, OK ranks among the best in the state, maintaining a remarkable average water quality score of 86/100 across its 2 ZIP codes. Based on recent EPA Safe Drinking Water Act compliance records, water provided by Davis and other municipal suppliers has consistently met or exceeded federal safety standards. This top-tier "A" grade reflects strong infrastructure, diligent monitoring by Oklahoma Department of Environmental Quality, and low contaminant levels.

The accumulation of 14 health-based violations over the past 5 years highlights systemic challenges within Davis's water infrastructure. When violations occur, it means that drinking water tests revealed contaminant levels exceeding safe limits, triggering mandatory corrective actions by Oklahoma Department of Environmental Quality. The city relies on surface water, which may require significant treatment upgrades to address these recurring issues.

Fortunately, the modeled risk for widespread lead exposure in Davis's municipal water is relatively low compared to national averages. However, because lead typically enters drinking water through the corrosion of older, individual home plumbing rather than the main supply lines, residents in homes built before 1986 should still exercise caution by running the tap before use.
